IMPORTANT DATA

Physical State; Appearance
VISCOUS COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Chemical dangers
The substance decomposes on heating producing toxic and corrosive fumes including acetic acid fumes, hydrogen sulfide and sulfur oxides. Reacts violently with strong acids and strong oxidants to produce hydrogen sulfide.

Occupational exposure limits
TLV not established.
MAK not established.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

Effects of short-term exposure
The substance is mildly irritating to the eyes and the respiratory tract.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: -18 - -10°C Relative density (water = 1): 1.18 Solubility in water, g/100 ml at 20°C: 100 Vapour pressure, Pa at 25°C: 0.43 Relative vapour density (air = 1): 4.22 Flash point: 160°C o.c. Auto-ignition temperature: 260°C Explosive limits, vol% in air: 1.2-5.2 Octanol/water partition coefficient as log Pow: -0.75

NOTES

The boiling point is higher than the autoignition temperature.
